Abstract

The present invention provides a filter cartridge for a vacuum cleaner. The filter cartridge comprises first and second opposite end walls, a side wall or walls which extend between the end walls so as to define an enclosure which surrounds a filter interior. One or more of the walls comprises filter membrane material. The cartridge has an opening provided through the first end wall for receiving air-entrained detritus into the interior, the opening being defined by a rigid support structure which spans and supports the first end wall of the cartridge. The rigid support structure of the first end wall comprises a central inner collar which defines the filter cartridge opening. A non-return valve is provided in the filter opening, which non-return valve is provided with resilient constraint means which is adapted to adopt an open configuration in response to a threshold reduced pressure in the cartridge interior, and which closes, or substantially closes, when the pressure reverts to ambient. The non-return valve comprises a flap of material which can deflect between a closed position in which the flap blocks the filter opening and an open position in which the flap is deflected away from the open position and into the filter interior. A shroud is provided around the filter opening, projecting inwardly into the filter interior from the collar which defines the opening. The filter cartridge may be collapsible to permit storage before use in a generally flat configuration.
